Comparing SQL to those other languages doesn't really make sense. Their purpose is different. For what SQL does, the syntax makes a lot of sense because it is a completely different paradigm. I think it's dismissive to refer to SQL as merely a 70s experiment. It is used so widely today still
I think SQL is amazing. There are few technologies within IT that has held up as well as it has. Skills you could gave learned 40 years ago still useful today. I think learning SQL well is one of the best investments you can do in yourself.
